I bought this RAM for my Y510P and it's working great: http://www.patriotmemory.com/product/detail.jsp?prodline=3&catid=93&prodgroupid=274&id=1359&type=5

Solid State Drive Firmware Update Utility for Windows 8.1 (64-bit), 8 (64-bit), 7 (32-bit, 64-bit) - ThinkPad - Lenovo Support (US) A non-fishy link ... I just updated my SSD to DSR2206 as well. The link says Thinkpad, but it worked great on my Y510P

The only way I was able to get it to sleep was to disable Bluetooth in the device manager. Once I did that, I was able to sleep the computer with the 7260AC card in it.

You are having the same problem many many of us are having with different brands of Lenovo laptop. There are quite a lot of posts about this, including one solution that involves replacing a MOSFAT on your motherboard ... https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Solution-for-laptop-cannot-detect-AC-adapter-after-performing/td-p/1641892 Short story is, it's a hardware problem usually brought about by running the battery calibration utility. The only current solution other than DIY replacement of an IC is to have Lenovo replace your motherboard.

Has anyone with a 7260AC upgraded to the modded v3.05 and been able to successfully get their wifi card to go to sleep without disabling Bluetooth?

Going from 1.07 to 2.07 solved my battery drain problem ... wondering if going to 3.05 will solve the battery charging issue where you have to unplug the battery and plug it back in to get it to charge again? Quite annoying and happens on both of my batteries.

That's exactly what I did. I installed the latest Intel wifi and bluetooth drivers for the card, and then went into the device manager, highlighted the "Intel® Wireless Bluetooth® 4.0 + HS Adapter" and disabled it. Seems to sleep now, but I didn't wait around a while to see if it remained sleeping. Basically I was just disabling different wifi features and hitting "sleep" over and over to see which thing did the trick. For example, it sleeps just fine if I put the laptop in Airplane mode (running Windows 8.1). From there I just started disabling things/re-enabling things until I got a combination that allowed it to sleep.

I just wanted to add my thanks to SVL7 for the whitelist mods. I have an early Y510P with the 1.07 BIOS. Experiencing the excessive battery drain problem when shut down, and sick of el-cheapo WiFi card. I found the 3.05 BIOS flash here: http://forum.techinferno.com/lenovo-ibm/5979-bios-update-y410p-y510p-74cn44ww-v3-05-a.html Then I backflashed it to 2.07 here (probably could've skipped the 3.05 update first, but didn't want to risk it): http://forum.techinferno.com/lenovo-ibm/5405-please-make-modded-y510p-bios-based-74cn44ww-v3-05-a-2.html#post77265 Then ran the whitelist mod on this thread so I could run my new 7260AC WiFi card. The updated BIOS fixed my excessive battery drain problem. I had tried everything prior to this. Removed the wifi card, removed the SSD, disabled WOL, disabled fast startup, new battery, Energy Management app, etc. Nothing fixed it until I flashed a newer BIOS, and I was losing at a rate of 1-2% per hour when completely shut down. BTW: Disabling Bluetooth on the 7260AC card solved the sleep problem as well. Not ideal, but I can live with it for now.
